 図6は、関連情報提示装置110の動作を示すフローチャートである。図6のフローチャートは関連情報提示装置110が利用者による検索式の入力を受け付けてから表示データを出力するまでの一連の処理を示す。図1乃至図6を参照して関連情報提示装置110の動作を詳細に説明する。 FIG. 6 is a flowchart showing the operation of the related information presentation device 110. The flowchart of FIG. 6 shows a series of processes from when the related information presentation device 110 receives a search expression input by the user until the display data is output. The operation of the related information presentation device 110 will be described in detail with reference to FIGS. 1 to 6.
 ユーザが関連情報提示装置110を利用して所望のコンテンツ情報を検索する場合、クライアント端末130のWebブラウザを利用して所定の操作を行なって検索用Webページにアクセスする。ユーザ操作に応じてクライアント端末130は検索用Webページの送信リクエストを関連情報提示装置110へ送信する。関連情報提示装置110は、クライアント端末130から送信リクエストを受信すると、検索用Webページを示すデータをクライアント端末130へ送信する。これにより、クライアント端末130の画面上にWebブラウザによる画面D1(図4参照)が表示される。ユーザは画面D1において検索フォームFに検索式を入力する。ユーザは検索フォームFに明確な検索式を入力してもよいし、曖昧な検索式を入力してもよい。そして、ユーザが検索ボタンSBを操作すると、クライアント端末130は検索フォームFに入力された検索式を関連情報提示装置110へ送信する。図6において、関連情報提示装置110の検索式入力受付部111はクライアント端末130から送信された検索式を受け付けると、当該検索式をコンテンツ特定部112へ送る(ステップS101)。 When the user searches for desired content information using the related information presentation device 110, the user performs a predetermined operation using the Web browser of the client terminal 130 to access the search Web page. In response to the user operation, the client terminal 130 transmits a search Web page transmission request to the related information presentation device 110. When the related information presentation device 110 receives a transmission request from the client terminal 130, the related information presentation device 110 transmits data indicating the search Web page to the client terminal 130. As a result, the screen D1 (see FIG. 4) by the Web browser is displayed on the screen of the client terminal 130. The user inputs a search expression to the search form F on the screen D1. The user may input a clear search expression in the search form F or an ambiguous search expression. When the user operates the search button SB, the client terminal 130 transmits the search formula input to the search form F to the related information presentation device 110. In FIG. 6, when the search formula input receiving unit 111 of the related information presentation device 110 receives the search formula transmitted from the client terminal 130, the search formula input receiving unit 111 sends the search formula to the content specifying unit 112 (step S101).
 関連情報提示装置110のコンテンツ特定部112は、検索式入力受付部111から検索式を受け取ると、当該検索式に基づいて1つのコンテンツを特定する(ステップS102)。例えば、検索式がキーワード「A社」を示す文字列の場合、コンテンツ特定部112は当該キーワード「A社」に合致するコンテンツ「A社」(図3参照)を特定する。例えば、検索式に複数のキーワード「企業」、「ソーシャルネットワーキングサービス」、「最大手」の論理積に係る検索条件が組み合わされている場合、コンテンツ特定部112は当該検索条件に合致するコンテンツを検索して特定する。その際、コンテンツ特定部112は関連情報提示装置110に格納されている情報源を参照して検索処理を行なってもよい。或いは、通信回線Nを介してアクセスし得る他のコンピュータに格納されている情報源を参照して検索処理を行なってもよい。そして、コンテンツ特定部112は特定したコンテンツ情報を間接的関連情報抽出部113及び表示データ表示部114へ送る。 When the content specifying unit 112 of the related information presentation device 110 receives the search formula from the search formula input receiving unit 111, the content specifying unit 112 specifies one content based on the search formula (step S102). For example, when the search expression is a character string indicating the keyword “Company A”, the content specifying unit 112 specifies the content “Company A” (see FIG. 3) that matches the keyword “Company A”. For example, when a search condition includes a combination of search conditions related to the logical product of a plurality of keywords “company”, “social networking service”, and “maximum”, the content specifying unit 112 searches for content that matches the search condition. To identify. At that time, the content specifying unit 112 may perform a search process with reference to an information source stored in the related information presentation device 110. Alternatively, the search process may be performed with reference to an information source stored in another computer that can be accessed via the communication line N. Then, the content specifying unit 112 sends the specified content information to the indirect related information extracting unit 113 and the display data display unit 114.
 関連情報提示装置110の間接的関連情報抽出部113は、コンテンツ特定部112で特定されたコンテンツ情報を受け取ると、間接的関連情報格納部116に格納されているコンテンツ情報のうち、特定されたコンテンツ情報に対応付けられたコンテンツ情報を抽出する(ステップS103)。ここで、間接的関連情報抽出部113は複数のコンテンツ情報を抽出してもよい。そして、間接的関連情報抽出部113は抽出したコンテンツ情報を表示データ生成部114へ送る。 When the indirect related information extracting unit 113 of the related information presenting apparatus 110 receives the content information specified by the content specifying unit 112, the specified content among the content information stored in the indirect related information storage unit 116. Content information associated with the information is extracted (step S103). Here, the indirectly related information extraction unit 113 may extract a plurality of pieces of content information. Then, the indirect related information extraction unit 113 sends the extracted content information to the display data generation unit 114.
 関連情報提示装置110の表示データ生成部114は、コンテンツ特定部112で特定されたコンテンツ情報と間接的関連情報抽出部113で抽出されたコンテンツ情報とを受け取る。表示データ生成部114は、コンテンツ特定部112で特定されたコンテンツ情報を示すノードN1と、間接的関連情報抽出部113で抽出されたコンテンツ情報を示すノードN2とをエッジEで結んだグラフG1を示す表示データを生成する(ステップS104)。表示データ生成部114は、表示データを表示データ出力部115へ送る。 The display data generation unit 114 of the related information presentation device 110 receives the content information specified by the content specifying unit 112 and the content information extracted by the indirect related information extraction unit 113.

A related information presentation device having a configuration according to the purpose of use can be constructed on the computer 900 by appropriately calculating and processing information by appropriately combining these specific means.
 例えば、コンピュータ900と外部装置との間で通信を行なう場合、CPU902はRAM903にロードされた通信プログラムを実行し、通信プログラムに記述された手続に従って通信インタフェース907に対して通信処理を指示する。通信インタフェース907は、CPU902の制御下、RAM903、ハードディスクドライブ908、フレキシブルディスク993、CD-ROM992などの記憶装置に設けた送信バッファ領域に記憶された送信データを読み出してネットワークへ送信したり、或いは、ネットワークから受信したデータを記憶装置に設けた受信バッファ領域へ書き込む。このように、通信インタフェース907はダイレクトメモリアクセス方式により記憶装置との間で送受信データを転送してもよい。或いは、CPU902が転送元の記憶装置又は通信インタフェース907からデータを読み出して、転送先の通信インタフェース907又は記憶装置にデータを書き込むことにより送受信データを転送してもよい。 For example, when communication is performed between the computer 900 and an external device, the CPU 902 executes a communication program loaded in the RAM 903 and instructs the communication interface 907 to perform communication processing according to a procedure described in the communication program. The communication interface 907 reads out transmission data stored in a transmission buffer area provided in a storage device such as the RAM 903, the hard disk drive 908, the flexible disk 993, and the CD-ROM 992 under the control of the CPU 902 and transmits it to the network, or Data received from the network is written to a reception buffer area provided in the storage device. As described above, the communication interface 907 may transfer transmission / reception data to / from the storage device by the direct memory access method. Alternatively, the CPU 902 may read data from the transfer source storage device or the communication interface 907 and transfer the transmission / reception data by writing the data to the transfer destination communication interface 907 or the storage device.
 また、CPU902はハードディスクドライブ908、CD-ROM992、フレキシブルディスク993などの外部記憶装置に格納されたファイル、又はデータベースに格納されたファイルの全部又は必要な部分をダイレクトメモリアクセス方式によりRAM903に読み込ませ、その後、CPU902はRAM903のデータに対して各種の処理を実行する。そして、CPU902は処理後のデータをダイレクトメモリアクセス方式により外部記憶装置に書き戻す。 Further, the CPU 902 causes the RAM 903 to read a file stored in an external storage device such as the hard disk drive 908, the CD-ROM 992, the flexible disk 993, or all or a necessary part of the file stored in the database into the RAM 903 by the direct memory access method. Thereafter, the CPU 902 executes various processes on the data in the RAM 903. The CPU 902 writes the processed data back to the external storage device by the direct memory access method.
 上記の処理において、RAM903は外部記憶装置の記憶内容を一時的に保持する記憶装置である。上述の実施例において用いられる各種のプログラム、データ、テーブル、データベースは記憶装置に格納されており、所定の情報処理が施される。また、CPU902はRAM903の記憶内容の一部をキャッシュメモリに保持しておき、当該キャッシュメモリ上でデータの読み書きを行なうようにしてもよい。この場合、キャッシュメモリはRAM903の機能の一部を担うため記憶装置に分類される。 In the above processing, the RAM 903 is a storage device that temporarily holds the storage contents of the external storage device. Various programs, data, tables, and databases used in the above-described embodiments are stored in a storage device and subjected to predetermined information processing. Further, the CPU 902 may store a part of the storage contents of the RAM 903 in a cache memory and read / write data on the cache memory. In this case, the cache memory is classified as a storage device because it has a part of the function of the RAM 903.
 また、CPU902はRAM903から読み出したデータに対してプログラム命令により指定された各種の演算、情報の加工、条件判断、情報の検索、情報の置換などを実行した後にRAM903に書き戻す。例えば、CPU902が条件判断を行う場合、各種の変数が他の変数又は定数と比較して、大きい、小さい、以上、以下、等しいなどの条件を満たすかどうか判断する。条件が成立した場合、又は条件が不成立であった場合に、他の命令に分岐したり、サブルーチンを呼び出したりする。 Further, the CPU 902 executes various operations designated by program instructions, information processing, condition determination, information retrieval, information replacement, and the like for the data read from the RAM 903, and then writes the data back into the RAM 903. For example, when the CPU 902 performs the condition determination, it is determined whether or not various variables satisfy conditions such as large, small, above, below, equal, etc., compared with other variables or constants. When the condition is satisfied or when the condition is not satisfied, the program branches to another instruction or calls a subroutine.
 また、CPU902は記憶装置のファイルやデータベースの情報を検索することができる。例えば、第1の属性に対して第2の属性がそれぞれ対応付けられた複数のエントリが記憶装置に格納されている場合、CPU902は記憶装置に格納されている複数のエントリの中から第1の属性が所定条件と一致するエントリを検索し、当該エントリに対応付けられた第2の属性を読み出すことにより所定条件を満たす第1の属性に対応付けられた第2の属性を取得することができる。 Also, the CPU 902 can search for information on files and databases in the storage device. For example, when a plurality of entries in which the second attribute is associated with the first attribute are stored in the storage device, the CPU 902 selects the first entry from the plurality of entries stored in the storage device. The second attribute associated with the first attribute satisfying the predetermined condition can be obtained by searching for an entry whose attribute matches the predetermined condition and reading the second attribute associated with the entry. .
